2 Claims.

This invention pertains to renovators of the type adapted to process fibrous filling materials such as cotton mattress filling and the like, and has for its objects:

First, to provide a machine wherein the fibers of the substance processed are torn apart and fiufied.

A second object is to provide a machine for the processes above stated, with a minimum of working parts, constructed in a manner so as to be strong and. substantial and not likely to break or get out of adjustment.

A third object is to provide a machine in which the flow of material can be regulated sov that balling up or cording of material will not take place.

Other objects will'appear hereinafter.

I attain the foregoing objects by means of the mechanism and construction illustrated in; the accompanying drawings in which,

Similar numerals refer to similar parts in allviews.

Heretofore machines have been made for fluifin carding and otherwise processing fibrous substances used for filling mattresses and the like, however, these machinestend to tear and cut the fibers and are not adequately provided with mechanism for removing dirt from the fibers as they are in fiuffed or expanded condition. The device hereinafter described receives the material to be treated at one end and immediately. cards it between the vertical faces of a thresher diskand a stationary retard. The material is then forced by fan blades over a thresher cylinder where it is subject to further fiufiing and threshing, and at th same time is blown outwardly against a fine screen such as will pass dirt; particles and (broken. fibers, and. the. like;

but-rinot the usablefibers. Thefiber being thus treated-expands a an. annular sheet or cylinder. around. the thresher cylinderand within. :a 5 cylindrical passageway until it reaches the dis.- charge. end-bystheediagonal position' of threshingteet-h on-the rotor-r At the outer endot the fine. screen. the .material is forced 'into'a .conical screeneda'area enclosed-by a coarse screen; from whence it is drawn'out and forced into-the discharge pipe. by ablower.

Outsideof the-cylindrical-flne screen a secnd dust removing-blowen. formed as a squirrel cage, rotates so as to draw an even draft throughout the entire Periphery of the fine screen. Dust and broken fibers forced 1 through this screen. are collected: withinathe outer case andthen-fun then collected .and-drawminto a hopper from which they; are discharged ,by another centrifugal-:fan:

Referring to the-specific construction; 2 indicates abox case which encloses the working parts. Operating onxa. longitudinal shaft 3, within this case-is the. main: cylindrical. thresher-rotor 4 which consists of two end disks and ii connected byv four; ra'ilsw l, which carry thresher teeth 8 arranged; in rows diagonally aligned relative to'the-v aXis'Qf the rotor. Between these'rails aresIa-tsforming fan blades l 0. Adjacent todisk 6 is a fiufiingor thresher disk l2.which carrie a large. number ofteeth' extending directly out-. ward: from its outer face. On the rim of this wheelarera number of-.wdiago nally:positicned fan blades-s14,-provided-withteeth on their outer edges,- and; havingmheir-outer corners ll beveled ofi-so; as to permit. free passage of material overetheir. outer-edges: These may be termed feed bladesr Positioned adjacent to disc l2 i-s-a stationary disk '20. attached tothe near edge-of the;.box:case.r Thispis termed a retard; and has teeth extending outwardlyirom .its inner face in. juxtaposition to-theteethon-disk l2. 1 A feed hole -|3:is cutin this -disk:=through. which the material to be processed is fed.

Surrounding themain. thresher rotor just described-is a fine screen-(Fig. 22. This is braced by. suitable means and on its inside pro vided with annular bafiles. or-riilles 23, to. slow up they progressofimaterial throughout its length.

- above described.

fan housing is a coarse screen 21 which has a I somewhat conical outer shape. The object of the annular area between the main rotor and the fine screen, and draw it into the discharge fan 25 without creating a suction on the material. while within said annular area, and without 7 drawing dust from it. V Annular races surround the ends of screen" 22 to accommodate rollers 32 ateitherend'of' the squirrel cage rotor, 33. ,At each end of this rotor there are large gear wheels 34 which are fore, the material discharge blower does not draw a draft thru this screen such as would be likely to pickup dust from the material being threshed;

It is to be noted thatthere is a partition 28 at the discharge end of screen 22 which supports that end of the screen and separates the dust receiving compartment 29 of the case from the area surrounding screen 21. This partition is cut horizontally so as to.be part of the upper and lower halvesof the outer case. ,Apartition 3| in the lower half of the case, acts as a support for the outer end 'of screen 21. The space between the retard 20 and rotor disk l2 may be driven by spur gears 35 on shaft 36, and this in turn is driven by pulley 31 connected by belt 38 to a driving pulley I 5 on shaft 3. The squirrel cage rotorrotates around screen 22in such a way as to create an even outward draft tocollect dirt and undesirable substances blown through screen 22 by the blades [0 on the main rotor 4. This material is drawn into the interior of case 2 and collects in pan 40, from which it is drawn by the blower 4| and discharged through pipe Shaft 43 isdriven by a pulley Shaft 3 is driven in any conventional manner from a convenient power source at about l200revoluti0ns per minute. I

Operation The machine is set up with power source driv- When shaft 3 rotates the other shafts 36 and 43 are driven by belt 38. The main thresher rotor 4 rotates in a clockwise direction, as viewed in Figures 1, 2, and 6. Squirrel cage gearing 44.'

blower operates ina direction to create an outward draft, as above explained. Material discharge blower 25 operates on shaft 3, and dust removing blower 4|, on the shaft and gearing 'Materialis fed through hole [3, Upon coming in contact with disk l2 it is threshedbetween the rotating teeth on thisdisk and the sta- Blower 40 is drivenby a shaft 43 through tionary teeth on the retard 20 and at the same time given a centrifugal action. As it nears the rims of these parts, it is caught by the diagonally positioned fan blades l4 and forced into the cylindrical area enclosed by screen 22. It proceeds along this annular working area due to the action of the rows of thresher teeth 8 diagonally arranged, as shown. These teeth are provided with right angular bends, at their ends,

forming hooks 41 pointing in the direction; of

rotation. This prevents rolling or cording of the material being'processed. The material is i subjected to a threshing action between teeth 8 on the rotor and teeth 24 on screen 22, and at the same time a beating and blowing action by the rotor blades l0. The'bafiies 23 hold the ma terial back so that it does not work thru the machine too fast. Thus the material is threshed and the dust and dirt blown out as it is forced along the length of screen 22.

After the material has reached the far or discharge'en'd of the annular space between roit has less resistance than thru screen 22. There-f termed a receiving chamber. rounding screen '21 may be left open since air is drawn inwardly'thru this case. Any suitable hopper orfeed mechanism may be attached to feed hole l3.

Whereas I have described one example of my invention, I realize it is subject to many modifications and substitutions, therefore I wish to be limited only by the following claims,

I claim: I V
